Start car, better with a mate, so he can blip the throttle.

Take your oil filler cap off and see if it is breathing heaps = indicates blowby = rings/liners worn. Keep a rag handy,so you can half cover the hole just in case it starts to spit oil.

Do it with a couple of cars if you can so you can see the difference.

And by breathing ill audibly hear air in the system? or it will blow oil around?

Ill give it a crack.

Apparently grabbed another gauge for the second test. I'm getting further tests out of curiosity. Leak down etc. And as previously mentioned.

If no good... Say hello fg xr6t. It's s bit of boat... But NEW

I agree. I will be. Im no mechanic mate, but of all tasks how complicated is a compression test. Remove components, put the gauge in and kick it over. repeat. How many variables for f**k ups can there be.

But yeah I'll be doing it anyway

At WOT?

At WOT?

I can only assume. This is the general practice yeah? Ill ask specifics this arvo.

There just isnt anything from the factory that has the same appeal. Closest is a turbo falcon. But it honestly feels like your driving a bus in comparison. Plenty of poke though out of the box ill give it that.

before i bought my r32 gtr, i compression tested afew that realy appealed to me.

i took them for a nice drive to get the engine hot, then did the compression test at WOT

my gtr came up 160 - 162psi accross each pot...

different methods will get different results

yeah do the test at running temp for starters, and full throttle, keep the test consistent across the cylinders for example if u hit 3 compression strokes on the 1st cylinder, do the same for the other 5, dont just keep cranking until it stops going up. if your still not sure do a leakdown test it will tell you everything a compression test doesn't.

yeah test drove one and gave it heaps. Manual fg. Goes great. Sounds good too. I was well impressed, but that feeling faded fast when I got back into the old skyline and realised I still f**king preferred it. Makes parting with the 50k painful.

Be nice if those clowns at Nissan released something comparable...

a skyline is a performance car an xr6 turbo is just a family car with a turbo slapped on

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
